The influence of the decompressive operation on the intracranial pressure and the pressure-volume relation in patients with severe head injuries.

1978

Measurements of intracranial pressure by ventricular catheter were performed in 47 patients with severe head injuries. Thirty-three patients with decompressive operations such as osteoclastic craniotomy and dilatation by means of duraplastic have been compared with 14 patients with closed heads with regard to volume pressure response (intracranial elasticity). This was determined either by intraventricular injection of 2 ml saline or by drainage of cerebrospinal fluid. The examination clearly shows that patients with closed heads have a much higher intracranial elasticity than patients who have decompressive operations, so that in the first group minor differences of the intracranial volume…

Self-reported flares are predictors of radiographic progression in rheumatoid arthritis patients in 28-joint disease activity score remission: a 24-m…

2016

Background Disease flares are common in rheumatoid arthritis (RA) and are related to structural damage. However, few data on the impact of flares reported by patients on radiographic progression are available. Our aim was to investigate whether overall flares (OF), self-reported flares (SRF) and short flares assessed at the visit (SF) predict radiographic progression in RA patients in DAS28 (28-joint disease activity score) remission. Methods We reviewed the records of RA patients included in our database. We considered all patients who had a period of at least 24 months in remission (DAS28 0. Patients were assessed every 3 months and flares were recorded. We defined SRF as any worsening of…

Upper Limb Interventions.

2019

Ultrasound has been reported to be a quick, cheap, and effective imaging modality to guide the interventional procedures in the musculoskeletal system. The use of ultrasound results in increased accuracy of needle placement associated with a reduction of complications. In the upper limb, ultrasound-guided procedures are applied to joints and soft tissues around the shoulder, elbow, wrist, and hand. This article reviews the clinical and technical aspects of the most common procedures performed in this anatomic area.

THE APPLICATION OF NEEDLE RADIOFREQUENCY FOR THE REDUCTION OF ACNE SCARS: A CASE STUDY.

2019

Background: Acne fulminans can leaveunsightly scars that can have a detrimental effect on a person’s ability to function in society, resulting in a deterioration in the overall quality of life of these patients. Scientific research shows that problems with self-esteemmay lower a person’s quality of life, making them reluctant to interact with other people.This, in turn, may lead to depression and, in extreme cases, to suicide. For people who suffer from acne fulminans, this is an extremely serious problem.This is compounded by the fact that even if they spend much of their life fighting acne, ultimately successfully, they still may be left with the visual effects of the disease, like scars.…

Šķidra metāla plūsmas un kristalizācijas izpēte ar neitronu radiogrāfiju

2019

Darbā pētīta orientētā kristalizācija, izmantojot neinvazīvu attēlveidošanas tehniku - neitronu radiogrāfiju. Rezultāti pirmo reizi atklāj daļiņu iesalšanas procesu metāla sacietēšanas laikā makro izmērā, ir parādīts, ka daļiņu iesalšana tilpumā notiek, kad cietā un šķidrā fāze veido pusšķidru maisījumu. Eksperimenti veikti ar alvu (Sn) taisnstūrveida traukā, kas tiek elektromagnētiski maisīta un orientēti kristalizēta. Informācija par recirkulējošo plūsmu ievākta, izsekojot 355 - 500 µm gadolīnija (Gd) daļiņas, kas vizualizē plūsmas lauku jebkurā laika momentā. Rezultāti liecina, ka metalurģiskās problēmas, piem., cieta materiāla iemaisīšanu kausējumā vai dielektrisku daļiņu vienmērīgā dis…

Electrocatheter-mediated High-voltage Pulsed Radiofrequency of the Dorsal Root Ganglion in the Treatment of Chronic Lumbosacral Neuropathic Pain

2019

Objectives: Despite the interest in scientific community, there is still poor evidence about pulsed radiofrequency (PRF) efficacy in the treatment of neuropathic pain. In order to determine whether high-voltage PRF and epidural adhesiolysis (PRF-EA) showed better results than epidural adhesiolysis alone (EA), a randomized, double-blind, comparative-effectiveness study was conducted in patients with chronic lumbosacral radiating pain and neuropathic features. Materials and Methods: A total of 41 patients were randomly allocated to 2 groups. Twenty-one patients were randomized to receive 2 cycles of 240 seconds high-voltage PRF followed by the injection of local anesthetics, hyaluronidase, an…

fMRI (Risonanza Magnetica funzionale)

Ruolo della Risonanza Magnetica funzionale nel panorama delle tecniche RM "avanzate".

Ipofisi

2012

Considerata l'elevata complessità anato-funzionale e le ridotte dimensioni delle strutture presenti nella regione sellare e ixuta-sellare, la parte introduttiva dell'intervento sarà obbligatoriamente dedicata a brevi richiami di fisiologia dell'asse ipotalamo-ipofisario, alla diagnostica di laboratorio (talvolta erroneamente considerata “di supporto” alla diagnostica per immagini) e all'anatomia radiologica; ciò consentirà di meglio comprendere la necessità di un assoluto rigore nei protocolli d'esame utilizzati per ottenere immagini di elevata affidabilità diagnostica. Sarà dato ampio spazio ai protocolli di studio e saranno discusse le principali indicazioni allo studio di tali dis…

Liver stiffness quantification in patients with non-alcoholic steatohepatitis: comparison of shear wave elastography and transient elastography with …

2019

Purpose: To assess the accuracy of liver stiffness quantification in patients with non-alcoholic steatohepatitis (NASH) using shear wave elastography (SWE) in comparison with transient elastography (TE). Methods and Materials: This is a prospective study performed in a single institution, including 49 patients with histological diagnosis of NASH. The stiffness of the right liver lobe was measured on the same day with two techniques: TE (FibroScan, Echosens), and SWE (RS80A ultrasound system, Samsung Medison). In the SWE evaluation, 11 patients were excluded due to more than 75% measurements fails. Receiver operating curves (ROC), areas under the ROC (AUROC) and 95% confidence intervals (CI)…
